This invention relates to the field of housing equipment, such as network servers, telephone switches, power supplies, and the like. More particularly, the present invention provides a new and useful method for monitoring such equipment when it is so housed.
Racks for housing equipment, such as servers, switches, routers, and the like are known in the art. With these types of racks, various components are rigidly secured by fasteners. The equipment will typically have a flange on each side which receives a threaded bolt which is used to secure the flange to a reciprocating threaded receptacle on the rack. The pieces of equipment are stacked one on top of the other. For example, on a typical eight foot rack, a telephone switch may be located in the bottom-most part of the rack. A server might be secured immediately above the switch. Then a router might be attached above the server, and so on. The height of such racks may vary dramatically depending on need. Oftentimes, the individual or organization using the equipment racks will assign a particular identifier for each device's position within each rack. For example, the switch at the bottom of the rack may be identified as U1. Immediately above that, the server may be identified as U2. A router stacked above the server may be identified as U3. Thus, the identifier for each rack will increase incrementally until the uppermost piece of equipment on the rack is identified. With the next rack, a new set of identifiers will be used (e.g., starting over again with U1).
Organizational problems oftentimes arise when numerous racks are in use by the same organization. Depending on the organizations communications requirements, it may manage hundreds—even thousands of racks full of servers, routers and switches. These racks may be located in one common place, or scattered in numerous locations geographically. Regardless of location, system administrators oftentimes have problems locating its racks. In fact, it is not all uncommon for an administrator to waste hours, even days searching for a rack that needs some kind of service.
Conventional racks also provide no support when it comes to the system administrator's problem of monitoring the battalions of servers, routers, switches and other equipment within vast arrays of racks. Most individual devices have visual indicators located thereon. These indicators visually inform the user of the failure of some internal mechanism. For example, when a fan goes out, an LED on the exterior of the server (or other device) will become illuminated so that the administrator can visually identify the problem and make the necessary repairs. Like indicators may be used for other sorts of problems, such as failed servers, hard drives, or to indicate that the device has unexpectedly “restarted” for some reason.
When an organization has vast quantities of racks in use at once, the identification of malfunctions by visual inspections of indicators is an overwhelming proposition. Because of this, monitoring systems have been used which enable the detection of equipment malfunctions automatically. It is also hoped when using such systems that the system administrator will be able to locate the particular piece of equipment within the facility including the vast quantities of racks.
One such prior method involves the creation of the client server relationship with an outside firm. With this client/server arrangement, software is installed on each independent piece of equipment within each rack. This special software monitors the functionality of the piece of equipment's hardware. This special software then contacts the server (an external organization) whenever there is a malfunction upon occurrence. The notification may also occur according to a predetermined schedule. The information regarding the malfunction is transferred by way of the already existing computer equipment. Once the server/external organization receives the information, that information, or whatever subset of that information the administration has preindicated a desire to have knowledge of, is transferred to the administrator. This is done so that the administrator may take any actions necessary based on the information.
A second prior art system is also software based. It, like the first, involves the installation of software in each particular piece of equipment. Unlike the first, however, this arrangement is Web-based. When some malfunction occurs, the software causes the system administrator to be contacted over the web directly. Usually via email.
Both of these prior art systems, however, have significant disadvantages. This is because they are dependent on the software within each piece of equipment for quick response to malfunctions. This requires that the device be reprogrammed every time that it is moved. If it is not appropriately reprogrammed, it will be difficult to locate it, especially when numerous racks are in place within a particular facility. Further, the operation of the software within the rack, obviously, is dependent on the functionality of the device. For example, without power, the monitoring systems within the device will obviously fail.
Another disadvantage in these systems regards asset tracking. Presently, the methods used to track rack mounted assets are separate from the monitoring systems. Thus, the conventional methods of accounting for these assets are very time consuming and costly.
The present invention overcomes the above-stated disadvantages in the prior art systems by providing an equipment housing which has a separate intelligent device disposed thereon, or proximate thereto. In the preferred embodiment, two interfaces are provided in the computing device. The first interface is used for sending and receiving information between a piece of equipment on the rack to the computing device. The second interface is used for sending and receiving information to an external system. With either interface, the information sent or received usually regards either the rack or the equipment disposed thereon. One example of such information might be the malfunction of particular device within a piece of equipment. Another might be the location of a particular piece of equipment in the rack. The computing device also includes a processing component. The processing component is used to manage the information. Also provided is a storage component. The storage component includes nonvolatile memory.
The housing includes a frame. The frame of the present invention has a base number, first and second substantially parallel upright numbers, and a substantially horizontal cross member for securing its upper end.
Information regarding the rack or equipment is transmitted via signals. These signals are transmitted between the equipment and the computing device through an information channel. The information channel is disposed on one or both of the upright numbers of the rack. More specifically, the information channel is a bus which leads from one or both upright numbers down into the computing device. In one embodiment, the computing device is located on the floor of the rack. The floor of the rack may also include a protective cover. The cover is used to form a protective shell in which the computing device is disposed.
The present invention is described in detail below with reference to the attached drawing figures, wherein:
The present invention provides a system and method for housing equipment such as servers, switches, routers, and other computer or telco equipment. A special computing device is used which is associated with, and preferably physically attached to, the housing itself. This small computer is used to identify each of the components on the rack geographically and locationally within the equipment housing. It is also used to monitor anything that might malfunction in any of that housing's equipment. Preferably, the computing device will be used to automatically identify components as they are transferred in and out of the rack. This should be done in a manner such that the computing device will always have knowledge of what is installed on its particular equipment housing and also include geographic information on where that equipment housing is located. This should be possible without having to program and reprogram each individual piece of equipment as it is placed into and removed from the housing. Instead, the computer equipped housing will automatically recognize the presence or absence of equipment. It also will automatically monitor equipment systems once they are installed into the housing with little programming required.
The computing device will always be associated with that particular rack, making it easy to identify the particular piece of equipment at issue when there is a problem, such as a malfunction with that equipment.
The housing of the present invention also comprises a frame. The frame has a base, a pair of substantially upright members, and a cross member joining the upright members. A bus is provided on each of the upright members. Each bus runs down to the computing device which, ideally, is attached to the base of the housing. These busses are electronically connected to, and interface with the computing device. Because the bus is located longitudinally all the way up the upright members, the connections between the equipment and computing device may be easily made.
Throughout the description of the present invention, several acronyms and shorthand notations are used to aid the understanding of certain concepts pertaining to the associated system and services. These acronyms and shorthand notations are solely intended for the purpose of providing an easy methodology of communicating the ideas expressed herein and are in no way meant to limit the scope of the present invention.
Further, various technical terms are used throughout this description. A definition of such terms can be found in Newton's Telecom Dictionary by H. Newton, 19th Edition (2003). These definitions are intended to provide a clearer understanding of the ideas disclosed herein but are in no way intended to limit the scope of the present invention. The definitions and terms should be interpreted broadly and liberally to the extent allowed the meaning of the words offered in the above-cited reference. For example, whereas some distinguish the World Wide Web (WWW) as a subcomponent of the Internet, “web”—as used herein—should not be construed as limited to the WWW. Rather, “web” is intended to refer generally to the Internet and/or its related networks and components.
As one skilled in the art will appreciate, the present invention may be embodied as, among other things: a device, a method, a system, or possibly a computer-program product. Accordingly, the present invention may take the form of a hardware embodiment, a software embodiment, or an embodiment combining software and hardware. In a preferred embodiment, the present invention takes all of the above-mentioned forms.

The equipment housing of the present invention is shown in detail in
Structurally, the housing includes a frame 10. Frame 10 comprises a first upright number 12, a second upright number 14, a base member 16, and a cross member 18. In the preferred embodiment, all of numbers 12, 14, 16, and 18 are comprised of metal. They could be, however, comprised of any material, which has properties, which satisfy the required structural and physical requirements for such a device. Thus, the frame of the present invention is not intended to be limited to any particular kind of material.
Frames with structures similar to those of frame 10 are known in the art. For example, it is known to provide a frame having two upright numbers, a base member, and a cross number to support computer, telephone-related, or other equipment. In fact, the particular frame construction of the present invention should not be considered as a limitation here. There is numerous equipment housing devices known in the art with which the devices and methods of the present invention could be utilized. Some examples of such devices include equipment cabinets, sliding racks, inter alia. The examples of housing devices, which could be used to accomplish the objectives of the present invention, are too numerous, in fact, to mention here. Such devices, however, would also fall within the scope of the present invention if used for the purpose of pursuing the invention's devices and methods.
The cross-sectional shape of upright members 12 and 14 is the same. As may be seen in
The upper ends of upright members 14 and 16 are shown in
At their lower ends, upright numbers 12 and 14 are supported and connected by base 16. Base 16 is shown here as a simple plate of metal. Other alternative configurations, however, would be evident to one skilled in the art. Thus, the actual configuration of base 16 is not considered to be limiting in any affect with respect to the present invention.
Base 16 is secured to floor 8 using fasteners 20. Fasteners 20 may be bolts, screws or any other fastening mechanism known in the art, which is used to secure frame 20 to the floor through holes, drilled in base 16. As mentioned above, frame 10 could be secured from above as well and still fall within the scope of the present invention.
Shown disposed in rack 10 in
Equipment such as server 22 will typically have a number of cables exiting from the backside thereof. Though these cables are not pictured, one skilled in the art of maintaining like equipment will know of them and how they appear. One of these cables is typically a power cord. This power cord (not pictured) is usually plugged into an outlet (also not pictured). The outlet may be located at some location external of the frame 10. Oftentimes, however, outlets are provided on the frame itself into which power cords may be plugged. Just because outlets are not shown in the
Besides the power cords, numerous other cables and/or lines also exit from the backside of each piece of equipment. These cables allow the equipment to perform its designated functions. With a typical server, very heavy data volumes may be handled in and out through these cables.
Immediately below server 22 in
Each of devices 22 and 24 are attached to rack 10 using a plurality of fasteners 26. These equipment fasteners 26 are screwed through flanges on the equipment. The flanges have apertures that receive the fasteners (e.g., bolts) there through. Once through the apertures, these bolts are received by a plurality of threaded receiving bores 28. It can be seen in
It will be abundantly apparent to one skilled in the art of caring for rack-mounted computer or telecommunications equipment that the
In typical rack arrangements, the lowest piece of equipment on the rack would typically be given an identifier, for example “U1.” The next piece of equipment above it would be identified as U2, and so on. Here, however, only two devices have been shown on the rack in order to better illustrate the equipment housing itself as well as the system-monitoring intelligent device. The details regarding the computing device and equipment housing will be discussed in more detail hereinafter.
With respect to the equipment-housing frame 10, referring now to
Though not shown from the side (like member 12 is in
It should also be recognized that, though the embodiment shown in

With respect to the particular devices used in the embodiment disclosed in
It is important to note, however, that though these particular devices are used in this instance, it will be abundantly clear to one skilled in the art that other types of arrangements for making the necessary connections could be used instead, and still fall within the scope of the present invention. For example, a USB or fiber optic arrangement could be made as well in order to accomplish the desired objectives. A wireless arrangement could also be used to interface between the computing device and equipment. In such a case, information channels would be unnecessary. Numerous other arrangements could be used also. Here, the prescribed devices have been selected simply because of low-cost and because high volumes of data transfer will not be necessary through the information channels 34 and 35.
It will now be described how the equipment disposed in the equipment housing, including server 22 and router 24, are connected to computing device 60 using information channels 34 and 35. This connection, with respect to server 22, is made using a data conduit 40. Data conduit 40 has two ends. At one end, conduit 40 has an equipment connector 44. Receptacles in which equipment connector 44 may be electrically connected with server 22 are oftentimes existent on the front sides of such devices. Such receptacles are commonly used for accessing the server via a lap top computer or some other kind of computing device. The receptacle on server 22 (not shown) is used to tap into channel 35 by snapping in connector 44. At the other end of conduit 40, a bus connector 46 is used to connect into one of the plurality of connectors 37 on information channel 35. Thus, using connectors 44 and 46, conduit 40 is able to make a serial connection between server 22 and information channel 35.
Again, this is a simple serial, or other types of connections may be accomplished in numerous ways known to those skilled in the art. In this embodiment, however, a simple serial connection is satisfactory considering that only small amounts of data will be transferred across conduit 40. This “smallness” is relative to the much greater traffic that is transmitted in and out of the equipment through the larger conduits emitting from its back (not pictured).
Router 24 is connected into information channel 34 in a similar manner. Referring to the embodiment shown in
Though the server 22 and router 24 in
The particular equipment-connection arrangement shown in
When a piece of equipment is connected into one of the information channels, and an initial connection is made, computing device 60 must be configured to send and receive the appropriate information from the equipment. As already specified, the equipment will have software already installed, or added, that is capable of monitoring the equipment's systems and has information regarding that equipment stored therein. When the computing device 60 is connected, and thus, given communicative access to the equipment, it must be configured to that particular piece of equipment. This may be done in one of two ways.
First, computing device 60 may be manually configured by a user. One skilled in the art of configuring computers will be able to do this. Such methods are not new. This may be done by interfacing with device 60 using a laptop computer or other means.
A second way of configuring computing device 60 to the particular piece of equipment occurs automatically. With the automatic method, a user will program computing device 60 to automatically configure to equipment when it is connected. For example, a large organization may have thousands of pieces of equipment on numerous different racks. The organization may install software on each of its owned pieces of equipment that works with software installed on each computing device 60 on each housing to accomplish this automatic configuration. Alternatively, the device manufacturer or OEM may pre-install the software required to auto-configure the computing device 60.
Computing device 60 will now be discussed in more detail. First, it is evident in
It is required, of course, for the devices to function that they be communicatively connected in some means, however. This communications connection could comprise an electrical connection (as shown in
It is also possible that in the electrical connection disclosed in the embodiment shown in
The channels will make an electronic connection with device 60 in a manner known to those skilled in the art. One familiar with the art will know how to make a simple serial connection to a computer such as the one used here as computer 60.
The details regarding the internal components of computing device 60 are shown schematically in
So that computing device 60 may communicate, two interfaces are created. The first is an equipment interface 106. This is the interface that is created through information channels 34 and 35. Equipment interface 106 is what is used to send and receive information to the equipment through the serial connection created through information channel 34 and 35.
The information communicated may be of a variety of types. The information could include, for example, information such as storage space available on hard drives within the device. Further, it could include a warning message that a device has malfunctioned on one of the pieces of equipment. Using router 24 as an example it may be observed that a plurality of fans 52 exists thereon. If one of fans 52 should malfunction, a message could be delivered to computer 60 through channel 34 by way of the equipment interface 106 so that processing component 102 (using memory component 104) could record this event. Another example of information that could be transmitted is that of a server being disabled. Further, information could be transmitted regarding whether one of the pieces of equipment has become unplugged or has power failure for another reason. All of this information would initially be received through interface 106. Another form of information can be transmitted is location information. For example, the equipment identifier (e.g., U1, U2, U3, . . . ) might also be received through interface 106.
Though the embodiments disclosed in
A second interface, external interface 108, is used for the purpose of giving the system administrator access to equipment information received by computing device 60. Access may be given by the system administrator in any number of ways. First, a port could be provided on the computing device 60 which would give the system administrator access to device 60 using a laptop computer in a manner known that will be evident to those skilled in the art. External interface 108 could also take the form of an internet or other type of network connection. Other forms of enabling the system administrator to interface with device 60 will be evidence to those skilled in the art and all fall within the scope of the present invention. Further, plural interfaces for making external connections may be existent on device 60 for a plurality of notification and accessing purposes. All of these arrangements would also fall within the scope of the present invention. The embodiment presented in
In the embodiment disclosed herein, computing device 60 is a microcomputer. Other types of computing devices, however could be used as well and still fall within the scope of the present invention.
One feature yet unmentioned, is that a computing device 60 must be powered by a power source of some sort. Batteries could, of course, be used for this purpose. It is more common, however, to use some kind of external power cord, which will be connected to the device. Though obviously necessary to made the computing device 60 function, it is not shown in any of the figures.
Another feature of the invention that has not yet been discussed, is the entity or entities by which the external interface might be used. One such entity might be a centralized computing system. Such a system might monitor a great number of equipment housing devices such as that disclosed as housing 10 in this application. Possibly hundreds or even thousands. This centralized computing system would be contacted by each computing device 60 on each rack in order that equipment information with respect to each rack would be maintained in such a manner that all equipment information (e.g., geographic locations, rack positions, working status) would be available to the system administrator at all times. Furthermore, the system could be used to enable the system administrator, by his or herself, or through the efforts of others to immediately (i) locate malfunctioning devices, (ii) ascertain the remaining capacity on any device, or any other equipment-related information desired.
Now that all of the devices and arrangements of the present invention have been disclosed, we will address the way in which the system works. One step in accomplishing the present invention, is that the organization will program each equipment device (e.g., server 22 and router 24) with software that is designed to recognize computing device 60. Likewise, computing device 60 will be programmed in such a way that it may interface with each piece of equipment. Such programming techniques will be within the scope of that known to those skilled in the art.
The software installed on the equipment will be designed to transport only very specific information to computing device 60. This will be information regarding the status of that particular piece of equipment. For example, its precise location in the rack, its available processing or memory space, or other hardware-related conditions that might be of interest to the system administrator. The information delivered could also be event-related. For example, whenever a fan such as fan 52 were to malfunction or “go out,” this information could simultaneously be passed on to computing device 60 through equipment interface 106. Computing device 60 could then store the event in memory component 104, so that the administrator could obtain this information at a later time. Alternatively, the fan-malfunction-message could be instantly delivered to the system administrator over interface 108 by the internet or other means of message connection. This would enable the system administrator immediately repair the condition because the computing device 60 will be able to inform him or her the exact geographic rack location and the exact equipment position within the rack such that time is not wasted.
It is important to note that though the preferred embodiment has been described as using a centralized computing center for monitoring all the racks operated by a particular organization, that the interfacing could be done in a much different way. Alternatively, a system administrator could simply move from rack to rack periodically and hook up to a port on computing device 60 to accomplish the interfacing. At this point, the system administrator would be able to retrieve the desired information into, say, for example, a laptop computer. Thus, the equipment could be periodically monitored.
Another advantage yet undescribed of the present invention is that of asset management. Because a centralized computing system operated by the organization would be able to immediately ascertain how many devices (equipment) were presently operating under the current system, the organization could easily ascertain how many units and what type of units were operating on the system currently without making an extensive accounting thereof. With the conventional systems, this is an arduous task. This is because a device will not appear on a system until it is programmed therein. These programming techniques have proved to be very unreliable and lack comprehensiveness. For example, it is not uncommon for a system administrator to “discover” a device in a rack, which has been abandoned, forgotten, or misplaced. The equipment housing of the present invention 10 would overcome these dilemmas.
Another advantage provided by the present invention is in the area of theft deterrence. With the equipment housing of the present invention, the system administrator may be immediately alerted if devices have been removed from their assigned racks. Because these devices, such as server 22 and router 24 tend to be very expensive, this is a very significant advantage as well.
As can be seen, the present invention and its equivalents are well adapted to provide a new and useful equipment housing which may be used to monitor equipment. Many different arrangements of the various components depicted, as well as components not shown, are possible without departing from the spirit and scope of the present invention.
The present invention has been described in relation to particular embodiments, which are intended in all respects to be illustrative rather than restrictive. Alternative embodiments will become apparent to those skilled in the art that do not depart from its scope. Many alternative embodiments exist but are not included because of the nature of this invention. A skilled programmer may develop alternative means of implementing the aforementioned improvements without departing from the scope of the present invention.
It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations and are contemplated within the scope of the claims. Not all steps listed in the various figures need be carried out in the specific order described.
